From 4be2a60b0ebb845c8f5043ef3f27b691a51df7c2 Mon Sep 17 00:00:00 2001
From: Paul Kocialkowski <contact@paulk.fr>
Date: Mon, 10 Aug 2015 23:53:48 +0200
Subject: [PATCH 6/7] firmware: Separate screen and wait at device information
screen
This blanks the screen (instead of redrawing it) at device information and
waits for the user to press any key to come back to the developer mode screen.
